Patented Dec. 17, 1907 Application-filed April15 1907. Serial No- 368.317.

To all whom it may concern:

-Be it known that of the United States, residing at Milton, in the county of Sumner and State of Kansas, have invented certain new and useful Improveme'nt's in Attachments for] Self-Propelled Vehicles, of specification.

This invention has for its object an attachment'f'or traction engines, automobiles, or

similar self-propelled vehicles whereby vehicle may pull itself free after having its wheels more orless embedded in a miry ro-a way, and the invention consists in certain constructions and arrangements of parts which I shall hereinafter fully describe and then point out the novel features in the appended claims; i

For afull description of the .invention and the merits thereof and also to acquire a knowledge of the means for effecting the result, is to be had to the following accompanying drawings, in which:

Figure 1 is a side elevation of a traction engine equipped with theimprovements of my invention; Fig. 2 is a front elevation thereof, parts being broken away. Fig, 3 is an enlarged fragmentary view illustrating, one of the means for journaling the shaft ofthe reel or capstanemployed. Fi 4 is a sectional view on the line a::r of ig. 3. Fig. 5 is a side elevation, on a reduced scale, i1 ustrati'ng the application of-the invention.

Corresponding and like parts are referred to in the followin description and indicated in. all the views 0 the drawings by the same reference characters;

Referring to the drawings, the numeral 1 designates the boiler of a, traction engine, and 2 the drive shaft thereof, with its fly wheel 2, said shaft being operatively connected to a gear ring 7 or the like on the rear driving axle, by means of the intermediate gears 3, 4, 5 and 6.

Hangers 8 are provided in which to 'ournal the transversely extending shaft 9 0 a reel or capstan 10. In the present instance these hangers have three branches, two of whic are connected to the boiler and the third of reference which is connected at its rear end to '.the

walls of the, boiler furnace. One of these branches may be use as a connectin means for the supportin brace 8 of the boi er.

In order that t e capstan may be detached whenever desired, the ournal bearings at the I, OsoAa SMITH, citizen q 'ries a gear which the following is a the. -sion 9 by means the details of construction of description and lines in Fig. 4,

drlve 'uncture of the arms or branches of the angers. are provided respectively with re movable sections '11.. secured in place by screws or bolts as shown. One end 9, of the capstan shaft 9 is extended as shown and carwheel 12 which may be splined for movement thereon, or'formed with a square openin receiving the end 9 of a correspondingsha t, and the gear w 'eel 12 is adapted to be held at different points along the extenlike. A rope 14 is adapted to be swung of a set screw 13, or the A around the capstan and to pass'forwardly underneath and in contact witha roller 14 which is journaled within the blocks 15 suspended by means of staple bolts or stirrups 16from the front axle 17. r The purpose of the roller 14" is to reduce friction, and to raise the front end of the engine when the front wheels are mired and to prevent the raising of the rear, end of the engine under the strain of the cable.

In describing the practical operation of the invention, reference is to be partlcularly had to Fig. 5, wherein is illustrated a traction en-.

of which have become embedded in the road way. In order to free the engine by its own power, the cable or rope 14 is unwoundfrom the capstan 10 and carried forward the required distance and secured to one or more stakes 18 driven into the ground. The engine is then started in a direction to wind up the cable upon the capstan, which will manifestly result in drawing the traction engine or other vehicle forwardly and practically lifting the embedded wheels from the road way.

As the gear wheel 12 is mounted for adjustment upon the extension 9 of the capstan shaft 9, it may be moved outwardly upon said extension, as indicated by dotted and be held at anino erative position out of engagement with t e gear wheel-5, or it may be moved inwardly and held by the set screw 13 in en agement with the gear wheel 5, so as to be riven directly therefrom, whenever it is desired to bring the capstan into play. form of clutch may screw 13.

It is to be understood that my invention is not limited to traction engines, but is applicable equally to automobiles and other self ropelled vehicles, and that thc capstan may ended or supported in any way from 'cle and be driven by any desired ine the rear wheels be substituted for the set the ve It is manifest that any train of gearing from the motor 01' engine of the vehicle.

Havin thus described the invention, what is claimed as new is: I

The combination with a self-propelled vehicle and its engine and boiler, of hangers sesured to and depending from the boiler in front of the rear travelingwheels 0f the vehicle, driving gears operatively connecting the engine with therear traveling wheels, a capstan shaft mounted in bearings in the han ers, a capstan mounted on said shaft; said bearings being providedwith removable sections whereby the ca stan and its shaft may be detached, one en of said shaft being extended laterally, a spur gear longitudinally slidable on the extension of said shaft and iment with one of the drive gears, and a cable adapted to wind on said capstan.

In testimony whereof I aflix my signature in presence of two witnesses. OSCAR SMITH. [1,. s.] Witnesses:
